DETAILED DESCRIPTION OF INVENTION

FIG. 1 gives a top cross-sectional view of the container according to the present invention. According to FIG. 1, vertical columns (2) are provided around the walls of the big bag in said container. The big bag's fabric is composed preferably of pockets in between one outer (1) and one inner (4) layers so as to maintain the vertical columns (2) for ensuring the fixation thereof (2). For stabilizing the vertical columns (2) in said pockets formed between said big bag fabrics (1, 4), the big bag fabric (1) is stitched along the columns at sections where the columns are present (FIG. 2). Although the big bag fabric (1) is provided in double layers along the periphery of the big bag according to a preferred embodiment of the present invention, it can nevertheless be designed in a single layer. In the latter case, pieced fabrics to be stitched to the big bag fabric at the sections only where vertical columns (2) are present may be adequate. According to an alternative embodiment of the present invention, the interior of the big bag fabric (1) may be covered by an impermeable liner (13) particularly for the transportation or stacking of fluid materials. According to another alternative embodiment, the entire fabric material may also be formed without such liner, but with a single layer of any plastic material known in the art like PE with a thickness of e.g. 1000 microns.

As illustrated in FIG. 1, said vertical columns (2) are brought together with the big bag fabric (1) so as to remain partially in and partially out of the rectangular shape of container according to the preferred embodiment of the present invention. If desired, it is possible to design said columns (2) so as to entirely remain in or entirely out of the rectangular formation of said big bag.

According to the preferred embodiment of the present invention, said vertical columns (2) are made in a hollow tubular geometry from any material such as plastics, cardboard of adequate rigidity. As illustrated in FIG. 2, fastening elements (15) are provided at the sections where vertically-extending columns (2) are present preferably at the big bag's central part of lateral surfaces, said fastening elements (15) being fixed from two ends to the outer surface of big bag by means of stitches (14). Prior to stitching, said fastening elements (15) are looped around the support blocks (16) of pallet (8) whereon the container is placed, so as to provide the interconnection between the container and pallet (8). Said fastening element (15) can be connected to any other proper section of the pallet (8) other than the support block (9). Said fastening element (15) can provide the connection between the container and pallet (8) in any other way, except said looping approach, so that one end of said element (15) is connected to the container and the other end to the pallet (8), as well. According to the preferred embodiment of the present invention, the pallet (8) placed under said container is a commercially-available standard pallet.

An alternative embodiment of the present invention is given in FIGS. 4 to 10. With respect to this alternative embodiment, some of the vertical columns are fastened to the pallet through slots or holes (9) formed on the pallet. Other vertical columns (2) not fastened to the pallet (8) are preferably located on the pallet so as to settle in easily detachable/attachable manner on a slot or hole formed on the pallet. In the latter case, the vertical columns not fastened to the pallet become movable in a swinging manner around the vertical axis passing through the slot. According to the density of material that may be placed into the interior cavity of vertical columns (2), these vertical columns (2) can also be placed freely on the pallet without any structural connection like such slots.

As illustrated in FIGS. 2 and 6, fixation bars (10) of adequate rigidity are provided, said bars (10) being fixed to the pallet (8) and becoming introduced into the interior cavities of vertical columns (2) essentially at the central points of pallet (8) edges. According to this alternative embodiment of the present invention, the fixation bars (10) can be fixed to the pallet (8) either by being passed directly through the holes (9) opened on the pallet (8), or as illustrated in FIGS. 8 and 9, by being passed through said holes (9) and then fixed by a pin (11) and fastener (12), so that the container (8) is prevented from sliding and falling down from the pallet (8) while being moved.

According to an alternative embodiment of the present invention, instead of using the fixation bars (10) the vertical pallets (2) on the central points on the pallet edges, or the entire vertical pallets can be fastened directly to the pallet, or the vertical columns (2) present at such points can be eliminated so that the fixation bars are used directly.

According to the preferred embodiment of the present invention, the vertical columns (2) wherein no fixation bars (10) are introduced do not have the function of avoiding the falling-down of big bags from the pallet while being moved, but have the function of encountering the loads originating from another container stacked thereon.

Another embodiment of the present invention may involve the introduction of one fixation bar (10) into each vertical column (2).

Material inlet into the container's big bag may be realized through an input stack (7) formed on the top face (6), and the material output can be performed by means of an output stack (not shown in figures) formed on the base part (5). Said stacks can also be adapted to the lateral walls.

The fabric (1, 4) of the container's big bag according to the present invention is relatively thinner, allowing the big bag to be easily folded when it becomes necessary to do so.
